Processing oxy_delete processing instruction

Post by **tmakita** » Sat Mar 29, 2014 6:01 pm

Hi,

I want to use oxy_delete processing instruction with my XSLT stylesheet.

[Source Document]

<?xml version="1.0" encoding="UTF-8"?>

<topic id="topic_v5d_3ly_hn">

  <title>Change tracking example</title>

  <body>

    <p>Mr. Abe's TPP<?oxy_delete author="toshi" timestamp="20140321T225157+0900" content="<term keyref="KAIKOKU_OPEN"/>"?>

      <?oxy_insert_start author="toshi" timestamp="20140321T225137+0900"?><term

        keyref="KAIKOKU_BREAK"/><?oxy_insert_end?></p>

  </body>

</topic>

<?oxy_options track_changes="on"?>

[Stylesheet]

Code: Select all

    <xsl:template match="processing-instruction('oxy_delete')" priority="2">

        <xsl:variable name="piText" as="xs:string" select="string(.)"/>

        <xsl:variable name="regX" as="xs:string" select="'author="(.+)" timestamp="(.+)" content="(.+)"'"/>

        <xsl:variable name="author" as="xs:string" select="replace($piText,$regX,'$1')"/>

        <xsl:variable name="timeStamp" as="xs:string" select="replace($piText,$regX,'$2')"/>

        <xsl:variable name="content" as="xs:string" select="replace($piText,$regX,'$3')"/>

        <xsl:message select="'author=',$author"/>

        <xsl:message select="'timestamp=',$timeStamp"/>

        <xsl:message select="'content=',$content"/>

    </xsl:template>

This template outputs following message:

Description: [Saxon-PE] author= toshi
Description: [Saxon-PE] timestamp= 20140321T225157+0900
Description: [Saxon-PE] content= <term keyref="KAIKOKU_OPEN"/>

As you can see, '<' , '>' and '"' are doubly escaped in $content.

Are there any ways to restore $content into XML fragment using XSLT stylesheet? I want parse it using parse-xml-fragment() function.

Regards,

Toshihiko Makita

Hi Toshihiko,

My colleague George created such a stylesheet a while ago, I'm attaching it below:

Code: Select all

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

    xmlns:saxon="http://saxon.sf.net/"

    xmlns:xd="http://www.oxygenxml.com/ns/doc/xsl"

    exclude-result-prefixes="xd saxon"

    version="2.0">

    <xsl:template match="processing-instruction()[name()='oxy_delete']">

        <xsl:variable name="c" select="substring-after(., 'content=')"/>

        <xsl:variable name="clen" select="string-length($c) - 2"/>

        <xsl:variable name="content">

            <xsl:text><tmp></xsl:text>

            <xsl:value-of select="substring($c, 2 , $clen)"/>

            <xsl:text></tmp></xsl:text>

        </xsl:variable>

        <xsl:variable name="xmlContent">

            <xsl:text><deleted </xsl:text>

            <xsl:value-of select="substring-before(.,

                'content=')"></xsl:value-of>

            <xsl:text>></xsl:text>

            <xsl:value-of select="saxon:parse($content)"/>

            <xsl:text></deleted></xsl:text>

        </xsl:variable>

        <xsl:element name="trackchange">

            <xsl:attribute name="revisionflag">deleted</xsl:attribute>

            <xsl:copy-of select="saxon:parse($xmlContent)/*/node()"/>

        </xsl:element>

    </xsl:template>

    

    <xsl:template match="node() | @*">

        <xsl:copy>

            <xsl:apply-templates select="node() | @*"/>

        </xsl:copy>

    </xsl:template>

</xsl:stylesheet>

It uses XSLT 2.0 and the Saxon 9 specific extension "saxon:parse" (it is used twice to remove that double escaping you noticed):
